Sunglaze Aluminium Rafter 100mm

The Sunglaze Aluminium Rafter 100mm is the backbone of the Sunglaze standing seam roof. It is a 100mm hollow aluminium section that both carries the panels and provides the fastening track they clamp into, so it replaces the timber or steel substructure you would otherwise need. It is the part that makes a Sunglaze roof self-supporting.

The hollow section gives the rafter high torsional rigidity with a clean, minimalist profile, and the top channel is precision-engineered so the Sunglaze panels join and clamp into it without screws through the sheet. That hidden fastening system is what produces the signature standing seam look and removes the leak path that through-fixings create.

Because it is extruded aluminium, the rafter will not warp, rot or need painting. It suits a high-end commercial walkway, a contemporary residential veranda or a durable carport, and its metallic finish complements the glass-like look of the solid polycarbonate panels. The 100mm depth also allows extended spans, which reduces the number of support posts you need.

What You Need To Complete The Job

The rafter is installed first, and the panels clamp into it. Finish the rafter ends with the Sunglaze Rafter End Cap, and complete the joints with the aluminium base, cap and cover. The full set and the panels are in the Sunglaze category.

Frequently Asked Questions

What does the rafter do in the system?

The rafter carries the weight of the panels and provides the track they clamp into. Because it is both structural support and fastening system, it removes the need for a separate timber or steel substructure.

How are the panels fixed to the rafter?

The panels clamp into the precision top channel of the rafter, so there are no screws through the sheet. The panels and joiners lock together and into the channel, which gives the clean standing seam finish.

What span can the 100mm rafter handle?

The 100mm depth is engineered for extended spans, which is what reduces the number of support posts needed. The actual maximum span depends on the panel, the load and the installation, so confirm the span with the project engineer or the manufacturer guidance for your setup.

Is the rafter rust proof?

Yes. It is extruded aluminium, which does not rust, warp or rot. That is why a Sunglaze roof stays maintenance free and does not need painting over its life.

Do I need the end caps?

Yes, at the exposed ends of the rafter. The end cap seals the hollow profile, blocks out insects and debris, and gives the rafter a clean, square-cut finish rather than an open end.
